MAGNETIC GEAR DEVICE

WIPO Patent Application WO/2014/109268

A1

Provided is a magnetic gear device for increasing the force transmitted between a first magnet array, a second magnet array and a magnetic body array. A magnetic gear device provided with: a cylindrical first magnet array in which multiple magnetic pole pairs are each disposed at substantially equal intervals in the circumferential direction; a cylindrical second magnet array disposed concentrically on the outside of the first magnet array so as to face the first magnet array and in which multiple magnetic pole pairs are each disposed at substantially equal intervals in the circumferential direction at a shorter pitch than the first magnet array; and a cylindrical magnetic body array disposed between the first magnet array and the second magnet array and in which multiple magnetic bodies (22) are each disposed at substantially equal intervals in the circumferential direction. The magnetic gear device is configured so that the distances between the multiple magnetic bodies (22) and the second magnet array are shorter than the distances between the multiple magnetic bodies (22) and the first magnet array, and the magnetic bodies (22) are wider in the circumferential direction on the first magnet array side than on the second magnet array side.
